4. Line Inputs:
Their sensitivity is –10dBV (316mV). CD, DAT, MP3, DVD Audio players, keyboards, tape
recorders, synthesisers, etc. and the signal from audio mixers can be connected to this type of input.
If the signal source is not the balanced type, care must be taken to ensure that terminals 1 and 3 are
short-circuited, terminal 2 being the active signal.
To adapt the output of this type of source, normally stereo, to the unit input (mono), the
Ecler professional cable range can be used, which is designed specially for this purpose:
CNX2RCAXLR2 (2xRCA to XLR), CNXRCAXLR2 (1xRCA to XLR) or CNXMJXLR2 (jack 3.5 mm to
XLR). These connections contain a device for adding the L+R signals of a stereo source and
converting them to mono.
5. Microphone Inputs:
The MICRO input is prepared for a nominal input level of -40dBV (10mV).
The microphones must be dynamic, with low impedance (from 200 to 600
Ω
) and mono.
This type of microphone is usually balanced but in the rare case of having a NON-balanced
microphone, terminals 1 and 3 must be short-circuited.
To connect the microphones to these inputs, the ECLER professional cable range can be
used, in the XLR/XLR format, with three optional lengths: 5, 10 and 20 metres:
CNXXLRXLR5 / 10 / 20.
6. Audio output connection (STACK OUT):
This is balanced, and has a male XLR3 connector. Its nominal level is -10dBV (316 mV).
This output can be used to connect the unit to another self-amplifying box or conventional external
amplifier, mixer or even a recording device. It should be considered that this output is affected by the
volume controls, so that in the event of having to connect various self-amplifying boxes, the last units
may become saturated. Be very careful with the levels when using this output.
Next to the connector there is a button to select the output signal between mix or from
input 2
7. Indicators:
The blue “ON” light indicates that the power amplifiers are correctly supplied with power.
Each of the inputs has an “SP” signal presence indicator. These indicators will light up
when there is a signal in the inputs that is higher than -35 dBV, and are very useful for checking the
level with which the external signal sources enter the unit.
Lastly, the "CLIP" indicator warns you that the power amplifiers are saturated due to
excess signal. To prevent distortion and prevent the speakers from becoming damaged, it is very
important that this indicate is off while the unit remains in normal operation.
8. Tone control:
The VERSO 8P, 10P and 12P have an efficient 3-band tone control system, with a margin
of action of –20 at +10dB in each one. The cut-off frequencies are 250Hz and 5.5kHz. For the best
result, do not make drastic equalisations, and it is recommended not to exceed a level of ¾ in each
band.
